I have downloaded DDSCAT 7.3.exe and also read user manual. However, as i am from experimental background i am facing a lots of difficulty in learning DDSCAT. Can anyone suggest me some basic tutorials to learn it. our prime objective are

1. making a correlation between experimental and theoretical data of synthesized silver nanoparticles.

2. How does the extinction spectra of AgNPs changed with size of particles.

3. How Near field properties are changed with size.

4. How plasmon of AgNPs interact with nearby radiating dipole and extintion spectra of combined system.

thanks in advance
